Application filed March 9, 1814. Serial No. 823,291.

To aZZ whom it may concern Be it known that I, Hownnn ll. BLOOD, a citizen of the United States, residing at Kalamazoo, ll'lichigan, have invented certain new and useful Improvements in. Variable- Speed Gearing, of which the following is o. specification.

This invention relates to improvements in variable speed gearing.

My improved variable speed gearing is especially designed by me for use in motor vehicles, particularly of the lighter or cycle car type, where light and compact transmission gearings are especially desirable, and I have shown the same as I have embodied itfor use in such a structure. lily improvements are, however, readily adapted for and embodied for use in other relations.

The main objects of this invention are: First: to provide an improved transmission gearing which is simple and compact in structure and comparatively light in we it. Second: to provide an improved transmission gearing having these el integcs in which the gearsnre brought into mesh with a. silding or axial inoveincnt. ".ihird: to pro vide an improved transmission gearing; which is very easily adjusted or cont *olled.

Further objects, and objects relating to structural details Will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawn forming a part of this specification, in wl'iich:
